Come to your heaven, you heavenly quires!
Earth hath the heaven of your desires;
Remove your dwelling to your God,
A stall is now His best abode;
Sith men their homage do deny,
Come, angels, all their faults supply.

Let Gabriel be now His groom,
That first took up His earthly room;
Let Michael stand in His defence,
Whom love hath link'd to feeble sense;
Let graces rock when He doth cry,
And angels sing this lullaby.

The same you saw in heavenly seat,
Is He that now sucks Mary's teat;
Agnize your King a mortal wight,
His borrow'd weed lets not your sight;
Come, kiss the manger where He lies;
That is your bliss above the skies.

This little babe so few days old,
Is come to rifle Satan's fold;
All hell doth at His presence quake,
Though He Himself for cold do shake;
For in this weak unarmèd wise
The gates of hell He will surprise.

With tears He fights and wins the field,
His naked breast stands for a shield,
His battering shot are babish cries,
His arrows, looks of weeping eyes,
His martial ensigns, cold and need,
And feeble flesh His warrior's steed.

His camp is pitchèd in a stall,
His bulwark but a broken wall,
The crib His trench, hay-stalks His stakes,
Of shepherds He His muster makes;
And thus, as sure His foe to wound,
The angels' trumps alarum sound.

My soul, with Christ join thou in fight;
Stick to the tents that He hath pight;
Within His crib is surest ward,
This little babe will be thy guard;
If thou wilt foil thy foes with joy,
Then flit not from this heavenly boy.
